Joke idea
The Light of the Third Moon
There is no third moon in the skies, but there is an image of the moon in the eyes of random peoples of the world not bound to the other moons. The third moon that they see is a phantasmal purple color and when they see it bright in the sky they can see the world around themselves as if the light was real. Those who can see the third moon possess but two traits beyond seeing the titular moon, they can create images of the moon that give off a fate purple light, and when in the imaginary light of their moon they are immune to the direct effects of other moons.
